Doubtt the coil pack will make that much of a difference. You do have the firing order correct?
The last poor running K engine i looked at turned out to be cam timing.
we've played around with it this afternoon and got really pi55ed off with it.
we searched the web to get an idea of the firing order off the XE coil pack and got it running - but its as rough as cack.
everything seems to going in the wrong direction
dry deck kit is severely incontinent
oil is oozing out the diff by the gallon - big, big puddle under the car after only a week
oil firing out the throttle bodies
flames lurching out the throttle bodies
whats so annoying is it seemed to be running pretty good on the dyno - all we've done is carefully plumb it into the subframe and wire it up and its terrible
all our hopes are with paul at exon and simon at morspeed who'll hopefully get it all sorted as it should be when we take her in for a start from scratch set-up next week.
